To catch up with this spring breeze of time travel and transformation, Xie Qingan took it. ——And it was in a Mary Sue black historical novel written in high school. The heroine's surname is Xie Qing'an, she has fair skin, good looks and extraordinary temperament. But here comes the problem: She did not become the heroine with the same name as her, but she wanted to be the heroine's second best, the one who dominates heaven and earth, the lovely white lotus female partner, Cen Yue. The original female partner died miserably because she acted like a bitch. In order to survive, she could only hug her husband's thigh tightly. But here comes the problem again: The third husband is a potential black man. He is innocent on the outside but dark on the inside. He is sick both physically and mentally. What's even worse is...
